 * In this chapter, we'll learn how to integrate JUnit and EasyMock together.

 * perform basic mathematical operations such as addition, subtraction,
 * multiply, and division. We'll use EasyMock to mock the dummy implementation
 * of CalculatorService. In addition, we've made extensive use of annotations to
 * showcase their compatibility with both JUnit and EasyMock.
